Provided is a packet processing device for an information-centric network. The packet processing device includes a packet transceiver configured to transmit and receive packets, and a packet processing unit configured to process a transmitted or received packet including a forwarding identifier that identifies information present in the ICN and corresponds to an IP address of a network node holding the information, and at least one sub-identifier that identifies child information of the information, in which the forwarding identifier is used to forward packets.

Packet processing device for IP-based information-centric network

A conventional handover method is performed in units of base stations, so that there is a problem in that a large amount of power for handover is consumed and implementation cost is high. Through dedicated protocol message exchanges between a user equipment and a network or between networks, resource availability of candidate networks is checked in advance, a handover target network is selected from among the candidate networks according to a result of checking, and the selected target network is designated as a network to which the user equipment is handed over.

Method of selecting target network for hand-over and method thereof

The present invention relates to a method in which a mobile node having mobility performs handover in a mobile communication system, and more particularly, to a fast handover method and system using network-based localized mobility management. According to an exemplary embodiment of the present invention, in a network access process between a mobile node and a base station, the base station sends a message allowing network access to the mobile node and a link-up message to an access router. Then, the access router sends a location registration message, which includes a mobile node identifier, a target base station identifier, a localized mobility anchor identifier, and access permission flag information, to a localized mobility anchor (LMA), and receives an acknowledgement (Ack) message including network prefix information. Accordingly, when a router advertisement (RA) message is sent to the base station, the mobile node performs duplicate address detection (DAD). Accordingly, fast handover is performed to reduce packet loss and delay that occur when the mobile node moves between networks, thereby minimizing the packet loss and delay.
